What is the maximum number of hours you are allowed by regulation to schedule your personnel?

• A. 8hrs
• B. 24hrs
• C. 40hrs
• D. 12hrs

Answer: (D)

Fatigue management is the idea behind this rule. Regulations cap how long a person can be scheduled to work in a single on-duty period to keep performance high and safety intact. The upper limit used in practice is twelve hours. That length gives maintenance teams enough time to complete tasks, handle handoffs between shifts, and still ensure a rest period before the next work period begins. If you ever need to go beyond twelve hours, the normal approach is to split the work among additional personnel or shift that task, adhering to overtime rules and required rest periods, with approvals for any exceptional cases.

Eight hours is a common standard shift in many contexts, but it doesn’t reflect the maximum allowed in regulation. Twenty-four hours or forty hours per day aren’t permitted as a continuous on-duty period, as they would significantly increase fatigue risk.
